The RadioLink PRM-01 is a compact real-time voltage telemetry module designed for seamless integration with 1S to 6S LiPo-powered RC models. Measuring only 33×22×11mm and weighing just 7g (0.25oz) including wire, it fits perfectly into mini racing drones, gliders, and other compact aircraft. When paired with RadioLink receivers and transmitters such as the R12DS or R9DS and AT10II/AT9S series, the PRM-01 delivers precise live voltage data directly to your transmitter screen—helping pilots detect voltage drops in time to prevent failure or damage.
